Method for preparing efficient titanium-based film material for treating wastewater

A method for preparing an efficient titanium-based film material for treating wastewater comprises the following steps that butyl titanate is mixed with absolute ethyl alcohol and triethanolamine to prepare a mixed solution A, and an additive needs to be added after the mixed solution A is evenly mixed; absolute ethyl alcohol and deionized water are mixed to prepare a mixed solution B, a catalyst needs to be added after the mixed solution B is mixed evenly, and the pH of the mixed solution B is regulated, wherein the regulating range of the pH is 3-4; the mixed solution A is slowly added into the mixed solution B, fierce stirring is carried out at the same time, the solutions are fully mixed, and alcosol is formed; the alcosol is uniformly smeared on the surface of a carrier, ageing is carried out for a period, alcogel is formed, then drying and sintering are carried out, and the titanium-based film material is formed.
